Klappentext zu „Elements of Molecular and Biomolecular Electrochemistry “
Written by two of the world's leading authorities in the field of electrochemistry, this book comprehensively addresses workhorse electrochemical reactions that serve as the basis of modern research for alternative energy solutions.* Provides an accessible and readable summary on the use of electrochemical techniques and the applications of electrochemical concepts to functional molecular-level systems
* Includes a new chapter on proton coupled electron transfer, a completely revamped chapter on molecular catalysis of electrochemical reactions, and added sections throughout the book
* Bridges a gap and strengthens the relationship between electrochemists, molecular and biomolecular chemists--showing a variety of functions that may be obtained by multi-component systems designed using the paradigms of both chemistries
